Abstract
Description
- (A) Field of the Invention
- The present invention relates to a light emitting diode (LED) lamp, and more particularly, to an LED lamp and heat-dissipating waterproof cover thereof with heat-dissipating and waterproofing functions.
- (B) Description of the Related Art
- In recent years, LEDs have demonstrated advantages of small size, low power consumption, long life, and endurance of vibration, and have been increasingly applied to various display applications. Due to recent increases in oil prices, LEDs with superior power saving efficiency may replace traditional lamps for illumination.
- In comparison with incandescent lamps, LEDs can reduce power consumption by more than 40%. Thus, LEDs are being introduced in various illumination fields as part of power-saving plans in every country.
- However, the high-power LED illumination lamp generates large amounts of heat. If the heat cannot dissipate efficiently, the efficiency and the lifetime of LEDs is limited.
- Current LED illumination technology has some limitations, including: (1) the lamp cannot provide a heat dissipating path for hot air passing through the lamp from bottom to top; (2) the waterproof cover of the lamp overlies the entire lamp, so that the heat exchange with cool air only occurs at the sides of the lamp, which is not advantageous to heat convection with vertical exchange behavior; (3) because of poor heat dissipation, heat accumulates at the center of the lamp more than at the edges; (4) the lamp does not provide function of drain and guidance of flow; (5) any increase in the size of the heat dissipating holes at sides of the lamp would increase heat dissipating efficiency, but would decrease the waterproofing and rainproofing capability; (6) a waterproof mechanism has to be combined with heat process, inducing high cost and lack of flexibility; (7) the heat dissipating efficiency of the horizontal fins of the lamp is not good; and (8) the heat dissipating fins enclosed by the waterproof cover cannot perform convection with external cool air.
- To maintain the heat-dissipating and waterproofing functions of the LED lamps at the same time is a difficult problem, and a breakthrough is needed to address both issues effectively.
- The present invention provides an LED lamp and the heat dissipating waterproof cover thereof, which have superior rainproof, waterproof and heat convection mechanisms, and can meet heat dissipating and waterproof requirements at the same time.
- The LED lamp includes an illumination apparatus and a heat-dissipating waterproof cover. The illumination apparatus includes LED modules, and the heat-dissipating waterproof cover is configured to cover the LED modules. The heat-dissipating waterproof cover includes a plurality of first drain members, and a first gap is formed between every two adjacent first drain members, so as to increase the heat-dissipating efficiency of the LED modules by air convection. Every two adjacent first drain members are partially overlapping in vertical to prevent the intrusion of water.
- In an embodiment, the first drain member comprises a drain surface and a groove connected to a side of the drain surface, and the drain surface is inclined toward the groove for guiding water on the drain surface into the groove.
- In another embodiment, the heat-dissipating waterproof cover further comprises a second drain member, and the second drain member is associated with the first drain member to cover the LED module. The second drain member is disposed at the center of the heat-dissipating waterproof cover, and the first drain members are symmetrically disposed at either side of the second drain member. The drain surfaces of the first drain members are inclined toward the second drain member.
- The LED lamp and the heat-dissipating waterproof cover provide not only air convection channels for increasing heat-dissipating efficiency of LED modules, but also a waterproof mechanism. Therefore, only the electrical body needs to be sealed or given anti-moisture treatment, so that the LED lamp can endure exposure to outdoor weather or rain.
- The objectives and advantages of the present invention will become apparent upon reading the following description and upon reference to the accompanying drawings in which:
-
FIGS. 1A and 1B illustrate an illumination apparatus of an LED lamp in accordance with the present invention; -
FIGS. 2A , 2B and 2C illustrate an LED lamp in accordance with an embodiment of the present invention; -

FIG. 4 illustrates a cross-sectional view along line 1-1 ofFIG. 3 ; and -
FIG. 5 illustrates an application for an LED lamp of the present invention. - The present invention relates to a light module. To clearly understand the present invention, the detailed device structure is discussed below. The implementation of the present invention is not restricted to that known by the people skilled in the art. Moreover, known devices may not be described below to avoid unnecessary limitations. The preferred embodiments are discussed in detail below. It should be appreciated, however, that the present invention provides many applicable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed are merely illustrative of specific ways to make and use the invention, and do not limit the scope of the invention.

FIGS. 1A and 1B illustrate anillumination apparatus 11, andFIG. 1B is the top view of the back of theillumination apparatus 11 shown inFIG. 1A . A plurality of strip-like LED modules 14 (five modules in this embodiment) are disposed on the housing 13 (seeFIG. 1A ), and a plurality ofLED devices 15 are formed on eachLED module 14 for illumination. A plurality offins 12 are formed on the side of theLED module 14 opposite to the side having theLED device 15. Thefins 12 are formed in thehousing 13 for dissipating the heat generated by theLED devices 15. In this embodiment, thefins 12 are plate-like and disposed along the longitudinal direction of theLED module 14 one by one, and each fin extends laterally on theLED module 14. A side of thehousing 13 is provided with aconnector 16 for being connected to a support and a power source. - An ordinary outdoor lamp usually emits light downwards, such that a rainproof cover would be formed above the
housing 13. However, the rainproof cover would encapsulate thefins 12 in thehousing 13; and although thefins 12 may be not completely sealed, the heat still cannot be dissipated efficiently. Therefore, the illumination efficiency of theLED device 15 is impacted and the lifetime of theLED device 15 is decreased. - In accordance with the present invention, a heat-dissipating waterproof cover is formed on the
illumination apparatus 11 to provide efficient heat convection for increased heat-dissipating efficiency. The cover has waterproof and drain functions, and therefore it can be applied for outdoor illumination. -
FIG. 2A illuminates anLED lamp 10 including theillumination apparatus 11 shown inFIG. 1 and a heat-dissipatingwaterproof cover 20. The heat-dissipatingwaterproof cover 20 is formed above theillumination apparatus 11. -
FIG. 2B is a top view of the heat-dissipatingwaterproof cover 20, andFIG. 2C is a side view showing thefins 12 below theillumination apparatus 11. In an embodiment, the heat-dissipatingwaterproof cover 20 includes a plurality ofdrain members 21. Thedrain members 21 are symmetrically disposed and correspond to cover thefins 12 of theLED modules 14. Thedrain member 21 includes adrain surface 30 and agroove 32. Thedrain surface 30 guides water such as rain into thegroove 32. Thedrain surface 30 of thedrain member 21 further extends above thegroove 32 of anadjacent drain member 21, i.e., there is an overlap between twoadjacent drain members 21 in vertical or the twoadjacent drain members 21 are partially overlapping, so as to prevent intrusion of rain. The heat-dissipatingwaterproof cover 20 may further include adrain member 22 disposed above thefins 12 of thecentral LED module 14. Thedrain member 22 has no groove; instead it guides rain into thegrooves 32 of the twoadjacent drain members 21 at either side. - In an embodiment, a
gap 17 is formed between every twoadjacent LED modules 14. Agap 18 is formed between thedrain surface 30 of thedrain member 21 and thegroove 32 of theadjacent drain member 21. Agap 19 is formed between thedrain member 22 and thegroove 32 of theadjacent drain member 21. In other words, thegap 18 andgap 19 are formed between the twodrain members 21 or between thedrain member 21 and thedrain member 22, and consequently theillumination apparatus 11 is not sealed and is open to air. Accordingly, thegaps fins 12. -
FIG. 2D is a side view of the LED lamp according to another embodiment of the present invention. The drain surfaces 30 of thedrain members 21 direct water in the same direction. As a result, all the drain members use the same design, so as to simplify the preparation of components. In practice, according to the disclosure of the present invention, the combination of various drain members capable of providing waterproofing and air convection is also within the scope of the present invention. -
FIG. 3 illustrates the details of thedrain member 21, andFIG. 4 is the cross-sectional view along line 1-1 ofFIG. 3 . Thedrain member 21 includes thedrain surface 30 and thegroove 32. A side of thedrain member 21 bends and extends downward and is connected to thegroove 32. More specifically, anextension portion 34 connected to thedrain surface 30 forms a sidewall of thegroove 32.FIG. 4 shows that inclined surfaces 35 are formed on thegroove 32 in the longitudinal direction, and eachinclined surface 35 extends out of thegroove 32 to formjoint plates 36 to be connected to the surface of thehousing 13. The angle between theinclined surface 35 and the bottom 33 of thegroove 32 is between 95 and 160 degrees for accumulating rain, and draining rain when the groove is full. -
FIG. 5 illustrates a streetlamp in accordance with an embodiment of the present invention. TheLED lamp 10 is placed at a front end of an extension portion of thestreetlamp pole 40. As a result, theLED lamp 10 is tilted, and thegrooves 32 are also tilted along the longitudinal direction, thereby allowing the rain accumulated in thegroove 32 to be drained through the inclined surfaces 35. - In addition to a streetlamp, the LED lamp of the present invention can be applied to illumination devices under eaves or at bus stops. In summary, as long as the
LED lamp 10 is installed to be tilted, it can drain water effectively and has superior heat-dissipating efficiency. - The above-described embodiments of the present invention are intended to be illustrative only. Those skilled in the art may devise numerous alternative embodiments without departing from the scope of the following claims.
